The cursor position calculation did not correctly account for the width
of Unicode text, resulting in the cursor being placed to far left in
scenarios with characters taking up 2 cells, such as in Chinese text.
Fix this by combining the entire line into a string and computing the
length of the resulting string using the `unicode-width` crate.
This is the first code in the main crate making use of `unicode-width`.
Eventually, we'll probably want to use it in more places, to get better
and consistent results.

The nix crate offers thin wrappers around these functions which allow us
to get rid of our own libc wrappers, reducing the amount of code marked
`unsafe`.
Part of #12380
The special exit handling when running with address sanitization no
longer seems necessary. Our tests all pass without it.
Similarly, the leak sanitizer suppression is no longer needed, since we
don't get any warnings when running our checks without it.
Because our Rust code no longer has any ASAN-specific behavior, we don't
need the `asan` feature anymore.
Closes#12366
This is an initial implementation of the cargo xtask approach
https://github.com/matklad/cargo-xtask
For now, the only xtask is "check", which can be triggered by running
`cargo xtask check`. It is a thin wrapper around `build_tools/check.sh`.

Now, the `fish_wchar` crate does not have any local dependencies, making
it easy to depend on it in other crates without worrying about cyclic
dependencies.
Additionally, remove the (non-fish) `widestring` crate as a direct
dependency of the main crate.
Now, only the `fish_wchar` and `fish_printf` crates directly depend on
`widestring`. `fish_printf` could also depend on `fish_wchar`, but I
left that as is since `fish_printf` was published, so depending on a
crate which is not published to crates.io does not seem like a good
idea.

Use the version in Cargo.toml instead.
Print a warning if the Cargo.toml version is not a prefix of the Git
version. This can happen legit scenarios, see 0dfc490721 (build.rs:
Use Cargo_PKG_VERSION if no version could be found, 2024-06-10)
but the next commit will fix that.
Also remove stale comments in git_version_gen.sh.
The needless_return lint was disabled almost two years ago, alongside
several other lints. It might have been helpful for porting from C++.
Now, I think we can enable that lint again, since omitting the returns
results in equivalent, more concise code, which should not be harder to
read.
The only manual changes in this commit are removing the lint exception
from `Cargo.toml` and removing the unnecessary returns inside `cfg_if!`
macro invocations (in `src/fd_monitor.rs` and `src/proc.rs`).
All other changes were generated by
`cargo clippy --workspace --all-targets --fix && cargo fmt`
Closes#12189
Breaks the build on OpenBSD.
This is another case of a nix feature being unavailable on some platforms,
so start documenting them.
This reverts commit d6108e5bc0.
Fixes#12192
